CONVERTER FOR of iron, cuprous compounds and precious To all whom it may concern:

Be it known that LMAnonL COLLIN, a citimetals remain in the converter. By invertzen of the Republic of France, and a resident ing the converter these fixed portions can be of 38 Rue Vignon, Paris, France, have incollected in tubs or trucks H by decantation. vented a new and useful Converter for the The elliptical form of the converter an Separation of the Fixed and Volatile Metals the arrangement of the blower with horithe same side as the chimthat it passes tangentially in front 0 the chimney thereby avoiding any projection of fixed materials so that the blower only carries off the zontal twyers on ney insure such a which is that it is elliptical or oval its chimney being located on the same si e o volatile materials in the dra the minor axis of the ellipse as the blower. What I claim and desire to secure by Let- This arrangement permits of effecting the ters Patent of the United States is complete separation of the fixed and volatile 1. A converter having a reaction chamber treated elliptical in vertical cross section, with the long axis of the ellipse horizontal in the normal position of the converter, a series 0 twyers extending from end to end of the chamber and opening horizontally into the lower ortion of the latter from one side only, together with a chimney arranged midway between the ends of the chamber and opening thereto substantially vertically above the metals contained in the complex ores in the converter.

In the accompanying drawing :'-Figure 1 is a side elevation of the converter. Fig. 2 is a plan view thereof. Fig. 3 is an elevation at right angles to the first, and Fig. 4: is a section on the line in Fig. 2.

The converter A of elliptical form is movable in the ordinary manner around trunnions a1 a by means of toothed sectors B and twyers, for the purpose described.

9 designates the twyers that are arranged horizontally, preferably in two or even three tiers in order to distribute the air more uniformly throughout the entire height of the mass to be treated.

This converter operates in the following manner: The crude and granulated ores are introduced with coke into the converter after thereto substantially vertically above the the latter has been kindled with a small twyers, together with means journaled in uantity of fuel. This charging is prefersaid side frames to tilt the converter to discharge the charge through stantially as describe In testimony where of name to this specification,
